BLAST FURNACE.

Application led September 15, 1926. Serial No. 135,576.

This invention relates to metallurgical joint seams 9 between the bricks of one` furnaces and, while not limited thereto, relates more particularly to blast furnaces, and has for its object 4the provision of a 5 blast furnace Vor thelike having a refractory lining composed of brick, tile, or similar ma terial laid up or arranged so that the long dimensions and joint seams extend vertically instead of horizontal as has been the standard practice. t

Heretofore when the block lining material of blast furnaces, such as bricks or tiles. was laid up so that the longdimensions and joint seams extended horizontally, the inajor portion of the joint seams extended horizontally or at right angles to the flow of the stock entering or descending in the furnace. When the stock was entered and descended in the furnace-with the lining arranged in the usual and standardmanner, the stock impinged against the longitudinal edges of the lining blocks and caused the blocks to break away or spall off, thus rapidly wearing away and weakening the blocks.

The present invention provides a lining having its major portion of joint seams eX- tending vertically and parallel with the flow of stock and, therefore, eliminates the major portion of the wear heretofore caused by the descending stock.

In the drawings, the figure is a sectional view through the upper portion of standard blast furnacestack with the lining laid up in accordance with my invention, the uper half of the figure shows the lining bricks laid up with the vertical joint seams staggered, while the lower half shows 'the joint seams in line.

Referrin more particularly to the draw- 0 ings, the etter A designates the furnace stack' as a whole, which is composed of a metal shell 2 having a refractory lining B and closed a't its upper end by a hopper 3 and bells 4 and 5.

In the up er portion of the drawing, the lining B is s own laid up in accordance with this invention and composed of elongated y rectangular bricks 7 of the usual design laid u in an endwise manner so that their long dimensions and joint seams 9 extend parallel with the vertical axis of the furnace and parallel with the flow of stock into and through the furnace. The bricks 7 are laid up in horizontal courses with the vertical course staggered with relation to the vertical joint seams 9 of the next adjacent courses. v

v A modified embodiment of 'this invention is shown in the lower art of the drawing, in which the lining B is composed of elongated rectangular bricks 7 b of the usual de sign laid up in an endwise manner so that their long dimensions and joint seams 10 extend parallel with the vertical axis of the furnacefand parallel with the flow of stock into and through the furnace. The bricks of this embodiment of the linin are a1?- ranged in vertical courses with their vertical l joint seams in alinement and their horizontal joint seams staggered with relation to the horizontal joint seams of the next adjacent courses.

By providing a furnace lining built in accordance with this invention, the major portion of the joint seams between the bricks will extend parallel to the vertical axis of the furnace andparallel to the line of flow of the stock into and throughthe furnace, and therefore, wear of the bricks will necessarily be reduced.

It will be understood that the term bricks as used in this application is mea-nt to include bricks, tiles or other block-like lining material.

While I have shown and described certain specific embodiments of my invention, it will be understood that I do not wish to be limited thereto since various modifications may be made without de artin from the scope of my invention as eiine pended claims.

I claim:

1. The combination with a metallurgica surface, of a refractory lining composed o major portion of their joint seams extend substantially parallel to the vertical axis of the furnace whereby the abrasion fromV stock entering and descending in the furnaceis materially decreased, and the strength of the blocks is preserved.

2. The combination with a metallurgical furnace, fof a refractory lining composed of elongated blocks, said blocks being laid up so that the long dimensions and joint seams extend substantially parallel to the vertical axis of the furnace whereby the in the apf 95, blocks, said blocks being arranged so that aA abrasion from stock entering and descending in the furnace is materially decreased, and the strength of the blocks isv reserved.

3. The combination with a last furnace, 5 of a refractory lining composed of elongated rectangular bricks2 said bricks being laid up so that the long dimensions and joint seams 'extend substantially parallel to the vertical axis of the furnace whereby the abrasion from stock entering and descending in the l0 furnace is materially decreased, and the strength of the blocks is preserved.

In testimony whereof, 1 have hereunto signed my name.

WILLIAM C. PARSONS.
